Implantable technologies are becoming more widespread for biomedical applications that include physical identification, health diagnosis, monitoring, recording, and treatment of human physiological traits. However, energy harvesting and power generation beneath the human tissue are still a major challenge. In this regard, self‐powered implantable devices that scavenge energy from the human body are attractive for long‐term monitoring of human physiological traits. Thanks to advancements in material science and nanotechnology, energy harvesting techniques that rely on piezoelectricity, thermoelectricity, biofuel, and radio frequency power transfer are emerging. However, all these techniques suffer from limitations that include low power output, bulky size, or low efficiency. Photovoltaic (PV) energy conversion is one of the most promising candidates for implantable applications due to their higher‐power conversion efficiencies and small footprint. Herein, the latest implantable energy harvesting technologies are surveyed. A comparison between the different state‐of‐the‐art power harvesting methods is also provided. Finally, recommendations are provided regarding the feasibility of PV cells as an in vivo energy harvester, with an emphasis on skin penetration, fabrication, encapsulation, durability, biocompatibility, and power management.

自供电植入式医疗设备:光伏能量收集综述。

可植入技术在生物医学应用中正变得越来越普遍,包括物理识别,健康诊断,监视,记录和治疗人类生理特征。然而,人体组织下的能量收集和发电仍然是主要挑战。在这方面,从人体清除能量的自供电可植入设备对于长期监测人体生理特征很有吸引力。由于材料科学和纳米技术的进步,依靠压电,热电,生物燃料和射频功率传输的能量收集技术正在兴起。但是,所有这些技术都受到包括低功率输出,体积大或效率低的限制的困扰。光伏(PV)能量转换因其更高的功率转换效率和较小的占地面积而成为可植入应用最有希望的候选者之一。在此,对最新的可植入能量收集技术进行了调查。还提供了不同最新功率收集方法之间的比较。最后,提供了有关PV电池作为体内能量收集器的可行性的建议,重点是皮肤渗透,制造,封装,耐用性,生物相容性和电源管理。
